How to Fill Out the TD1 Form in Canada: 2026 Guide

When you start a new job in Canada, one of the very first pieces of paperwork your employer will hand you is the TD1 form — the Personal Tax Credits Return. This form determines how much income tax your employer deducts from each paycheque. Filling it out correctly is essential: claim too few credits and you'll have too much tax withheld (though you'll get a refund at tax time); claim too many and you could owe money when you file your return. For newcomers unfamiliar with the Canadian tax system, the TD1 can seem confusing — but it's actually quite straightforward once you understand what each line means.

What Is the TD1 Form?

The TD1, officially called the Personal Tax Credits Return, is a form that tells your employer which personal tax credits you are claiming so they can calculate the correct amount of income tax to withhold from your pay. There are actually two TD1 forms you need to complete:

• TD1 Federal: The federal personal tax credits return, which applies across all of Canada.
• TD1 Provincial or Territorial: A separate form for your province or territory of employment, since each province has its own tax rates and credits.

You can download both forms from the CRA's TD1 forms page. Your employer may also provide printed copies or digital versions through their onboarding system.

The TD1 is not a tax return — it does not determine how much tax you ultimately owe. It only affects the amount of tax withheld from your paycheques throughout the year. Your actual tax liability is determined when you file your annual T1 General income tax return.

When Do You Need to Fill Out a TD1?

You are required to complete a new TD1 form in the following situations:

1. When you start a new job. Every new employer needs a TD1 from you.
2. When you want to change the amount of tax deducted. If your personal situation changes (marriage, new dependents, additional income), you should submit an updated TD1.
3. When you want to increase tax deductions. If you have additional income from another source (freelance work, rental income) and want to avoid owing taxes at year-end, you can request extra tax be withheld.

If you do not submit a TD1 to your employer, they are required by law to withhold tax as if you are claiming only the basic personal amount — the minimum credit everyone receives. This means you could have more tax withheld than necessary, especially if you have dependents or other credits to claim.

Line-by-Line Guide to the Federal TD1

Let's walk through each line of the 2026 federal TD1 form. The amounts listed below are based on the 2026 tax year — check the current year's TD1 form on the CRA website for the exact figures, as they are indexed to inflation annually.

Line 1: Basic Personal Amount

Every Canadian resident is entitled to the basic personal amount (BPA) — the amount of income you can earn before any federal income tax is owed. For 2026, this amount is approximately $16,129 (the exact amount may vary slightly based on indexation). Everyone fills in this line. If your total income from all sources will be $173,205 or less, you claim the full enhanced BPA. If your income will be higher, a reduced amount applies. As a newcomer starting your first Canadian job, you will almost certainly claim the full amount here.

Line 2: Canada Caregiver Amount for Eligible Dependant or Spouse

If you have a spouse, common-law partner, or eligible dependant who is dependent on you because of a mental or physical infirmity, you can claim an additional credit. This is a specific and relatively uncommon claim — only fill this in if it applies to your situation.

Line 3: Age Amount

If you will be 65 years of age or older on December 31 of the current tax year, and your estimated net income is below a certain threshold (approximately $44,325 for 2026), you can claim the age amount. The maximum federal age amount is approximately $8,790. This is reduced if your income exceeds the threshold. Most newcomers starting their careers in Canada will not claim this line.

Line 4: Pension Income Amount

If you will receive eligible pension income during the year (such as from a registered pension plan, RRSP annuity, or certain foreign pensions), you can claim up to $2,000. If you're receiving a pension from your home country that qualifies, you may be able to claim this credit. Consult a tax professional if you're unsure. For newcomers interested in retirement savings, our RRSP guide for newcomers covers the basics.

Line 5: Tuition (Full-Time and Part-Time)

If you are a student enrolled at a designated educational institution in Canada and paying tuition, you can claim your tuition fees on this line. Only the portion of tuition that exceeds any scholarships, bursaries, or other educational assistance you receive should be entered. This is particularly relevant for international students who have transitioned to permanent residency and are continuing their studies.

Line 6: Disability Amount

If you have a severe and prolonged impairment in physical or mental functions and have been approved for the Disability Tax Credit (DTC) by the CRA, you can claim this amount. You need a completed and approved Form T2201, Disability Tax Credit Certificate, signed by a qualified medical practitioner.

Line 7: Spouse or Common-Law Partner Amount

If your spouse or common-law partner's net income for the year will be less than the basic personal amount (approximately $16,129), you can claim the difference. For example, if your spouse just arrived in Canada and won't be working for several months, their income may be very low, allowing you to claim a significant credit here. If your spouse has an infirmity, the Canada caregiver amount may apply as an addition.

Line 8: Amount for an Eligible Dependant

If you are single (or separated) and support a dependent relative who lives with you — such as a child under 18 or a parent or grandparent — you can claim the eligible dependant amount. This credit is essentially the equivalent of the spousal amount for single-parent families. You cannot claim both the spousal amount and the eligible dependant amount.

Line 9: Canada Caregiver Amount for Dependant(s) Age 18 or Older

If you support a dependant aged 18 or older (other than a spouse) who is dependent on you because of a mental or physical infirmity, you can claim this credit. This might apply if you are caring for an elderly parent who has come to Canada with you.

Line 10: Amounts Transferred from Dependant

If your dependant is a student or has a disability, they may have unused tax credits (such as tuition or disability amounts) that can be transferred to you. Enter the total transferred amount on this line.

Line 11: Total Claim Amount

Add up all the amounts from Lines 1 through 10. This is your total claim amount. Your employer will use this figure to determine how much federal income tax to deduct from each pay period. The higher your total claim amount, the less tax will be withheld from each paycheque.

The Provincial/Territorial TD1

In addition to the federal TD1, you must also complete a provincial or territorial TD1 for the province or territory where you are employed. The structure is very similar to the federal form, but the credit amounts differ because each province and territory has its own tax rates and credit amounts. For instance, Ontario's basic personal amount may differ from British Columbia's or Alberta's.

The key lines on the provincial TD1 generally mirror the federal form — basic personal amount, spousal amount, dependant amounts, disability amount, tuition, and so on. The main difference is in the dollar amounts, which reflect provincial tax legislation. You can find all provincial TD1 forms on the CRA website alongside the federal form.

Special Situations for Newcomers

Arriving Mid-Year

If you start working in Canada partway through the year, a common concern is whether you should claim the full basic personal amount on your TD1, since you won't be earning a full year's income. The answer is generally yes — claim the full amount. The basic personal amount is a full-year credit regardless of when you started working. Since you'll likely earn less than the basic personal amount in your first partial year, claiming the full credit ensures your employer doesn't over-withhold. For more details on proration rules, consult the CRA's personal income tax rates page.

Multiple Jobs

If you have more than one employer at the same time (which is common for newcomers working multiple part-time jobs), you should only claim the basic personal amount on the TD1 for one employer. For your other employer(s), check the box on page 2 that says you have more than one employer and enter $0 for your total claim amount. This prevents under-withholding of taxes, which could leave you owing money at tax time.

Additional Tax Deductions

On the back of the TD1 form, there is a section where you can request that your employer withhold additional tax from each pay period. This is useful if you have other income — such as freelance earnings, rental income, or foreign income — that won't have tax withheld at source. By requesting extra deductions on your TD1, you can avoid a large tax bill when you file your return.

Common Mistakes to Avoid

Here are the most frequent errors newcomers make when completing the TD1:

• Not submitting the form at all: If you don't submit a TD1, your employer withholds tax based on the basic personal amount only, potentially over-deducting.
• Claiming credits you're not entitled to: Only claim credits that genuinely apply to your situation. Overclaiming can result in a tax bill at year-end.
• Forgetting the provincial form: You need both the federal and provincial TD1. Some employers only provide the federal version — ask for both.
• Not updating after life changes: Got married? Had a child? Spouse started working? Submit a new TD1 to reflect your updated circumstances.
• Confusing TD1 with T1: The TD1 is the employer form for payroll deductions. The T1 General is your annual income tax return filed with the CRA — they serve entirely different purposes.

How Your TD1 Affects Your Paycheque

Understanding the connection between your TD1 and your take-home pay is important for financial planning. Your employer uses your total claim amount from the TD1, along with the CRA's payroll deduction tables, to calculate how much federal and provincial income tax to withhold from each pay. The higher your total claim amount, the less tax is withheld, and the more you take home each pay period.

However, keep in mind that the TD1 only affects income tax withholding. Your employer also deducts Canada Pension Plan (CPP) contributions and Employment Insurance (EI) premiums from your pay. These deductions are mandatory and are not affected by your TD1 claims. Understanding these deductions is important when you receive your T4 slip at tax time.

Digital Submission and Record-Keeping

Many employers now accept TD1 forms electronically through their HR portals or onboarding software. Whether you submit a paper or digital version, make sure to keep a copy for your records. You don't need to send the TD1 to the CRA — it stays with your employer. However, having a copy helps you remember what credits you claimed, which is useful when filing your annual tax return.

Key Takeaways

The TD1 form is a critical piece of your employment setup in Canada. Here's what every newcomer should remember:

1. Complete both the federal and provincial TD1 when starting a new job.
2. Claim every credit you're entitled to — don't leave money on the table by only claiming the basic personal amount.
3. Only claim the basic personal amount once if you have multiple employers.
4. Update your TD1 whenever your personal circumstances change significantly.
5. Request additional deductions if you have other income sources without tax withholding.
6. Keep a copy of your completed TD1 for your records.

By filling out your TD1 correctly from the start, you'll ensure the right amount of tax is deducted from your paycheques, avoid surprises at tax time, and take full advantage of the personal tax credits available to you as a Canadian resident.
